UAV Routing in Power Line Rights of Way
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The widespread adoption of UAV delivery is hindered by the challenge of routing to meet safety objectives and avoiding collisions, particularly due to the limited vertical airspace available under FAA regulations and the need for efficient navigation around obstacles like power lines.
Innovation Solution
Utilizing power line rights of way for UAV routing provides a clear, uninterrupted path to buildings, segmenting traffic by airframe glide ratio and speed to enhance safety and throughput, while leveraging existing infrastructure for energy recharging and navigation, and employing alternating electric field strengths for geofencing and navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UAVs operate under FAA altitude limits of 400 feet, then regulatory compliance is achieved, but vertical separation between drones is insufficient to ensure safety
Solution Approach 1:
The patent transitions from vertical airspace separation (3D height-based separation) to horizontal corridor-based separation using power line rights of way. By routing UAVs along designated 2D corridors defined by power line easements, the system achieves sufficient spatial separation without requiring vertical layering, thus complying with the 400-foot altitude limit while maintaining safety margins.
Solution Approach 2:
The patent divides the airspace into distinct segments by routing UAVs along separate power line rights of way corridors. Each corridor serves as an independent flight path segment, allowing multiple UAVs to operate simultaneously in different geographic segments without conflict, thereby achieving throughput enhancement while maintaining safety.
2Adaptability or versatility
If UAVs fly over roadways to reach buildings, then delivery coverage is expanded, but collision risk with obstacles and people increases
Solution Approach 1:
The patent uses power line rights of way as intermediary corridors that provide indirect routing around obstacles. Instead of flying directly over roadways and populated areas, UAVs navigate along the intermediary path defined by power line easements, which naturally route around buildings and people while still enabling delivery to target locations.
Solution Approach 2:
The patent extracts UAV flight paths from hazardous zones (roadways and populated areas) by utilizing power line rights of way. This removes UAVs from environments with high collision risk while maintaining delivery capability, as the extracted paths follow utility corridors that bypass people and vehicles.
3Productivity
If multiple UAVs share the same airspace, then delivery throughput increases, but collision risk between drones increases
Solution Approach 1:
The patent segments the airspace into multiple independent corridors based on power line rights of way. Each corridor can accommodate UAV traffic independently, allowing parallel operations of multiple drones without interference. This segmentation enables high throughput while maintaining collision avoidance through physical separation of flight paths.

AI summary
Using power line rights of way for UAV routing provides a direct, uninterrupted, aerially clear path to the vast majority of lots and buildings from nearby substations and generating stations. Segmenting or separating the UAV traffic by airframe glide ratio improves safety for people on the ground and utilization of the limited airspace. Further segmenting UAV traffic by airframe speed and size allows greater traffic throughput.
